Hydrazide compound and thrombopoietin receptor activator

ABSTRACT

Compounds effective for preventing, treatment or improving diseases against which activation of the thrombopoietin receptor is effective are provided. 
     A compound represented by the formula (I) (wherein R 1 , R 2 , R 3 , L 1 , L 2 , X and Y are defined in the description), a tautomer, prodrug or pharmaceutically acceptable salt of the compound or a solvate thereof.

TECHNICAL FIELD

The present invention relates to preventive, therapeutic and improving agents having affinity for and agonistic action on the thrombopoietin receptor for diseases against which activation of the thrombopoietin receptor is effective. Specifically, it relates to pharmaceutical compositions comprising compounds which increase platelets through stimulation of differentiation and proliferation of hematopoietic stem cells, megakaryocytic progenitor cells and megakaryocytes or compounds for therapeutic angiogenesis or with anti-arteriosclerosis action that stimulate differentiation and proliferation of vascular endothelial cells and endothelial progenitor cells.

BACKGROUND ART

Thrombopoietin is a cytokine consisting of 332 amino acids that increases platelet production by stimulating differentiation and proliferation of hematopoietic stem cells, megakaryocytic progenitor cells and megakaryocytes mediated by its receptor and therefore is promising as a drug for hematological disorders. Recent reports that it stimulates differentiation and proliferation of vascular endothelial cells and endothelial progenitor cells have raised expectations of therapeutic angiogenesis, anti-arteriosclerosis and prevention of cardiovascular events (for example, non-patent document 1, non-patent document 2 and non-patent document 3).

Biologically active substances which have been known so far to regulate platelet production through the thrombopoietin receptor include, in addition to thrombopoietin itself, low molecular weight peptides having affinity for the thrombopoietin receptor (for example, patent document 1, patent document 2, patent document 3 and patent document 4).

As a result of search for nonpeptidic low molecular weight compounds that increase platelet production mediated by the thrombopoietin receptor, low molecular weight compounds having affinity for the thrombopoietin receptor have been reported (for example, patent document 5 to patent document 26).

DISCLOSURE OF THE INVENTION Problems that the Invention is to Solve

Thrombopoietin and low molecular weight peptides having affinity for the thrombopoietin receptor are likely to be easily degraded in the gastrointestinal tract and are usually difficult to orally administer. As to thrombopoietin itself, the appearance of anti-thrombopoietin antibodies have been reported.

Besides, though it is probably possible to orally administer nonpeptidic low molecular weight compounds, no practical drugs have been put on the market.

Therefore, orally administrable low molecular weight compounds having excellent affinity for and agonistic action on the thrombopoietin receptor as preventive, therapeutic and improving agents for diseases against which activation of the thrombopoietin receptor is effective have been demanded. Specifically, low molecular weight compounds which can serve as platelet increasing agents or increasing agents for other blood cells by stimulating differentiation and proliferation of hematopoietic stem cells, megakaryocytic progenitor cells and megakaryocytes or low molecular weight compounds which can be used for therapeutic angiogenesis or as preventive and therapeutic agents for arteriosclerosis by stimulating endothelial cells and endothelial progenitor cells have been demanded.

Means of Solving the Problems

The present inventors conducted extensive research to find low molecular weight compounds having affinity for and agonistic action on the thrombopoietin receptor, and as a result, found that the compounds of the present invention have high affinity and agonistic action which enable them to show potent platelet increasing action by stimulating differentiation and proliferation of megakaryocytic progenitor cells and megakaryocytes. The present invention was accomplished on the basis of this discovery.

Assay Example 1 Stimulation of Proliferation of a Thrombopoietin-dependent Cell Line

The responses of thrombopoietin receptor to the compounds of the present invention prepared in the Synthetic Examples were assayed using a human leukemic cell line, UT7/EPO-mpl.

(1) Cells and Cell Culture

UT7/EPO-mpl is a stable transformed cell line obtained by introducing into human leukemic cell line UT7/EPO a vector that induces expression of human thrombopoietin receptor (c-mp1) under control of cytomegalovirus immediate-early promoter by the method of Takatoku et al. (J. Biol. Chem., 272:7259-7263 (1997)). Proliferation of this cell line is stimulated by TPO, while its mother cell line UT7/EPO exhibits no response to TPO. These two cell lines were subcultured in IMDM (GIBCO) containing 10% fetal bovine serum (Thermo Electron or BioWest) using a CO₂ incubator (5% CO₂, 37° C.).

(2) Cell Proliferation Assay

The subcultured cells described above were washed twice with PBS and suspended in IMDM containing 10% fetal bovine serum at a cell density of 6×10⁴ cells/ml. The cell suspension was transferred to a 96-well tissue culture plate (CORNING) in 100-μl aliquots. Then either thrombopoietin (Pepro Tech EC) or the compounds of the Synthetic Examples dissolved in dimethyl sulfoxide were diluted 83-fold with IMDM containing 10% fetal bovine serum and added to the aforementioned cell suspension in 20-μl aliquots. The cell suspension was incubated in a CO₂ incubator (5% CO₂, 37° C.) for 4 days. Cell proliferation was assayed using WST-8 reagent (Kishida Chemical Co., Ltd.) according to instructions by the manufacturer. A 10-μl aliquot of 5 mM WST-8 reagent solution was added to each well of the tissue culture plate, and the plate was incubated at 37° C. for 4 hours. The formazan pigment generated was detected by measuring the absorbance at 450 nm with a 96-well microplate reader (Nihon Molecular Devices, Spectramax 190). Proliferation of thrombopoietin-responsive UT7/EPO-mpl cells was stimulated by the compounds of the Synthetic Examples in a concentration-dependent manner, while no effect of this compounds on proliferation was observed with UT7/EPO, the mother cell line. These results indicate that the compound of the Synthetic Examples of the present invention acts on the thrombopoietin receptor selectively as an activator.

The concentration of each compound that yields a growth rate corresponding to 50% of the growth of human leukemic cell line UT-7/EPO-mpl observed in the presence of 10 ng/mL TPO (EC₅₀) in the test on the compounds of the Synthetic Examples in Assay Example 1 are shown in Table 16.
